Hi Milad,
Direct use of dwinormalise individual is not very typical; dwinormalise group itself internally calls dwinormalise individual, and that component was made accessible at the command-line rather than just embedding the code in case it is of use to anyone, but it’s not typically accessed directly.
If using that approach, you would typically want to use dwinormalise group before estimating response functions, since it will better balance the magnitudes of the response functions across individuals prior to computing the group average. That’s less consequential now due to the internals of how responsemean works, but it’s still logically the better sequence of steps.
Cheers
Rob
